Diapers

Three taps. One hand. In the dark.

Logging should be quick enough that it does not become another job. Feed. Pump. Diaper. Sleep. Solids. Medication. Temperature. Teeth. Bath. Tap what happened and get back to your baby.

You can also keep medication, temperature, teeth, and baths in the same place as sleep, diapers, growth, and the rest of the day.

The point is not to turn parenting into data entry. The point is to stop important details from living in five different places or only in someone's memory.
